Claims.

This invention relates to improvements in window and door ventilators, which are more particularly adapted for use with storm windows and doors of the type used in cold weather that are interchangeable with screens for use in Warm Weather. il l An object of the invention is to provide ventilating means for' windows and doors of the type referred to which can be quickly and easily adjusted to control the amount of air or ventilation passing therethrough.

Another object is to provide a ventilator of the typefreferred to comprising a fixed panel having openings therein and a movable panel having similar openings which may readily be moved into and out of registration or into partial registration Withthe openings in the fixed panel, with novel means being provided to hold the movable panel vin any selected position.

A further object is to provide novel means for controlling th-e movement of the movable panel.

Other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawing lIn the-drawing: j

Fig. V1 is a fro-nt elevation oi the lower portion of a storm window or door sash with my ventilator incorporated therein;

Fig. 2 is a sectional view taken substantially on line 2-2`of'Fig. 1 andgshowing the ventilating arrangement inY closed position;

Fig. 3 is a similar view showing the ventilating arrangement in open position; and

Fig. 4 is a perspective View of the means for raising, lowering and holding the movable panel.

Referring to the drawing the numeral I0 designates the side members and the numeral iI the bottom member of a door or Window sash which isvusually rectangular in shape but which is broken away herein atthe top for the sake of clearness. The sash is adaptedvto be itted in the customary supplemental frame (not shown) and to beused in conjunction with and outwardly ora-conventional window or door (not shown) of-a dwelling, as will be readily understood.

' Space'dfrom the bottom sash member II is an intermediate sash member I2 joined to the side members I0 in any suitable manner. Window glass (not shown) is adapted to be arranged in the sash above the member I2 in the usual manner. As more clearly shown in Figs. 2 and 3 the rear portion of the space between members II and I2 is filled with a iiXed panel I3 having a plurality of spaced, horizontal and preferably inclined openings I. Panel'IS may be cemented or otherwise suitably held in xed position.

The front portion I5 of the space between sash members II and I2 is adapted to receive a panel I e of less width than the space I5 and of slightly less length than said space so as to be movable from the position shown in Fig. 2 to that in Fig. 3 and vice versa. A plurality of horizontal, pre-ferably inclined openings Il are provided in the movable panel I6, similar in length and arrangement to the openings Ill. It will be apparent that the panel I6 may be moved from the closed position shown in Fig. 2, wherein the openings I4 and I6 are no-t in alignment, to the open position shown in Fig. 3, wherein these openingsV are in alignment, or vice versa, and by means of mechanism tol be described may be held at any position intermediate those shown in Figs. 2 and 3. Preferably it is desirable to secure a screen or the like, such as shown at I8 in Fig. 1, over the front central portion of panel I6 so as to cover the openings Il and prevent the entrance of insects or foreign matter through the ventilator, but this screen may be placed that will secure the same result.

Means are provided to move the panel I 6 vertically within the space I5 and to hold it in any selected position within said space. As more clearly shown in Figs. 1v and 4, a stamped metal bracket, vindicated as a Whole by the numeral I9, is secured by means of screws 2i)v or the like to the front face of each of the sash members Il). Each bracket I9 is formed with an inwardly directed portion 2| which bears againstthe inside face 22 of members I0 and is provided with a plurality of spaced openings 23. Each bracket I9 is also provided with an extension 24 arranged parallel with the sash members I i), said extensions terminating in depressed-portions 25 which frictionally engage the front face of panel IB and hold it against forward displacement without, however, `preventing vertical movement of the panel. y

Substantially centrally of each bracket I9, a gear or pinion segment 26 is pivoted to panel I6, as indicated at 2l, and the teeth 23 are adapted toA be received in the openings 23. An arm A29A is formed on'each segment 26 and is pro-vided with an outwardly extended portion 3U which` permits the arms to be readily grasped by an operator to raise or lower the movable panel I 6. These arms pass under the extensions 24 and do not interfere with the frictional engagement of the ends 25.

In operation the teethV 28 of the segments are at other points
